Use the library catalog to search for the JOURNAL'S name.
If WUSTL has the online journal, follow the full text links.

If not online, return to the catalog's list to see if WUSTL has the journal in paper format.
If WUSTL has the paper journal, consider requesting the volume (approx. 4 business days to arrive at your pick-up location).  The system will email you Ready for pick-up. Monitor the status through My Catalog.  Scan the article for free at a print-release station.  Note: some journal volumes cannot be requested.

If WUSTL does not have the item, consider requesting the article from the ILLiad interlibrary loan system (approx. 2 business days to arrive).  The system will email the PDF's link to you.  Monitor ILLiad requests by logging into your ILLiad account.
